sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
The “Thickened Tailings Disposal” (TTD) technology produces a high density mine waste that allows for the storage of this material without need to manage large slurry tailings facilities (TSFs) and dams. TTD has been applied considering site specific conditions Chile Peru, such as extreme climatic conditions, seismic risks, water scarcity, community demands, environmental constraints. This revi...
The failure of tailings dams causes ecological damage and economic loss can cause casualties. simulation the tailings’ spill path in event dam failures (TDFs) mitigate risk by provision spatial information for disaster prevention preparedness. In order to close gap between basic one-dimensional spill-path routing models complex numerical models, this paper examines an empirical model based on f...
Tailings produced during bitumen extraction from surface-mined oil sands ores (tar sands) comprise an aqueous suspension of clay particles that remain dispersed for decades in tailings ponds. Slow consolidation of the clays hinders water recovery for reuse and retards volume reduction, thereby increasing the environmental footprint of tailings ponds. We investigated mechanisms of tailings conso...
altogether 20 groundwater samples were collected around the lakan pb and zn mine in iran. samples were analyzed for 8 constituents including fe, pb, hg, mn, zn, cn, so4 and cl using standard method. the results show that the average concentrations of constituents were 0.01, 0.60, 0.10, 0.01, 0.40, 35, 0.01 and 5.95 mg/kg for fe, mn, pb, zn, hg, so4, cn and cl, respectively. the computed contami...
Abstract Tailings dams retain the waste by-products of mining operations and are among world’s largest engineered structures. Recent tailings dam failures highlight important gaps in current monitoring methods. Here we demonstrate how ambient noise interferometry can be applied to monitor performance at an active using a geophone array. Seismic velocity changes less than 1% correlate strongly w...
OBJECTIVE Unreclaimed mine tailings sites are a worldwide problem, with thousands of unvegetated, exposed tailings piles presenting a source of contamination for nearby communities. Tailings disposal sites in arid and semiarid environments are especially subject to eolian dispersion and water erosion. Phytostabilization, the use of plants for in situ stabilization of tailings and metal contamin...
Elevated inorganic phosphate (Pi) concentrations in pore water of amended tailings under direct revegetation may cause toxicity in some native woody species but not native forbs or herb species, all of which are key constituents in target native plant communities for phytostabilizing base metal mine tailings. As a result, Pi sorption capacity has been quantified by a conventional batch procedur...
